OPIMISAION DE 611 carries out a double metering of degree-days : 20 = metering of degree-days with reference to conventional ambient temperature of 20 C. Amb = metering of degree-days with reference to actual ambient temperature (with detector B3) or to that calculated (without B3). Start and stop at variable times so as to obtain the desired ambient temperature in coincidence with the times of start and end of occupancy. Useful for buildings with discontinuous occupancy such as : schools, business and public offices. he method for establishing the time of optimised start depends on the presence or not of the ambient detector Optimisation with ambient detector he start time is established by the meeting point of the descending curve of the actual ambient temperature (with plant OFF or in SEBACK/FROSPRO mode) and the ascending of ambient temperature curve defined by the parameter Start inertia. With Start inertia on AUOMAIC (15.4) : if the desired ambient temperature is obtained too soon or too late in respect of the required time, the controller corrects the start time for the following day by ± 15 minutes until the desired time is obtained. 10

15 18.7 Recording data For each plant controlled, at each change of mode and every two hours, the controller records a series of data indicating the operational status of the plants controlled : Current time, current day, type of recording (change of mode or end of two-hour period); current mode, actual outside temp.,compensated flow temp., desired and actual flow temp, desired and actual ambient temp., anticondensing temperature. Status output relays. It is able to memorise 28 complete recordings. he last recording brings about the cancellation of the oldest one. If the first page is not displayed the controller makes the recording at the end of the two-hour period but not the recording at the change of mode because it presumes changes to the setting data are in progress. he recordings can be viewed only by the telemanagement computer. 19. ALARMS he alarms processed by the controller are of three types : alarms for abnormal functioning of the controller and of the heating zones controlled; alarms for short or open circuits of the detectors connected; alarms from external contacts. he alarm status is indicated by the LEDs on the controller facia and is identified, on the page Detector Alarms, by the letter A alternating with the number of the alarm concerned. With the C-Bus setup alarms can be sent to a local PC and / or to the telemanagement central PC Functional alarms 28.6 Func t i ona la l a rms 8 he functional alarms are triggered in the presence of prolonged differences between actual measured values and those desired. hese alarms, with the exception of the real time clock alarm (8), do not affect the operation of the controller Factory setting : all disabled except for real time clock alarm (8). With + and keys enable the alarms required by replacing the dashes with numbers. When the number blinks = alarm triggered he limit values and delay times for sending the alarms can be changed only by PC. ype and cause of alarm : 1 = difference temperature heating flow (B1) enabled when pump M1 in operation 2 = difference temperature boiler (B4) enabled when burner in operation triggered when actual temperature below that desired 3 = difference ambient temperature (B3) enabled with NORMAL modes and with outside temperature below desired ambient temperature. triggered when actual temperature below or above that desired. 4 = boiler overtemperature (B4) triggered when actual temperature above maximum limit temperature 5 = DHW temperature (B5) enabled when pump M2 in operation triggered when actual temperature below desired temperature 6 = flue gases 1 temperature (B6) enabled if input B6 is configured as FLUGAS + ALARM triggered when actual temperature above maximum limit temperature 7 = flue gases 2 temperature or active detector mA (B7) enabled according to configuration of input B7 triggered when actual temperature above maximum limit temperature or when actual measurement mA exceeds for at least one minute the minimum or maximum thresholds set 8 = internal real time clock (cannot be disabled ) triggered when clock assumes meaningless values Detector alarms he detector alarms are triggered in the event of short or open circuits De t ec t o r A l a rms Using + and keys, disable unrequired alarms replacing the numbers with dashes ype of alarm and effect : 15

Factory setting : all disabled. Enable alarms of interest by replacing dashes by numbers using + and keys. When the number blinks = alarm triggered. If not used as alarm they can be used as status indicators. 20. COMMISSIONING PLAN esting to be carried out on completion and testing of installation, wiring and configuration esting C-Ring he page of C-Ring testing appears only if configured YES in Ensure that all the other controllers wired in C-Ring are : 28.3 CRing Connection YES 29.1 CR i ng :?? correctly powered by mains voltage (230 V ~) Slave controllers or configured as SECONDARIES in selected on testing page 29.1 CR i ng :?? 28.3 CRing Connection: SECONDARY he PRIMARY controller (Cont. 1) sends via C-Ring a signal every five seconds ; on all the displays appears??. Each controller checks the incoming signal ; if the connection is positive the word YES replaces?? on all the displays. If on one or more displays YES does not appear, this indicates that there is an open connection between the last controller with YES and the first with?? ; or, in the event that YES does not appear on any display, this indicates that there is an open circuit between the first controller and the second. Examples of testing a C-Ring circuit with four controllers : Cont.1 "YES" Cont.2 "YES" Cont.3 "YES" Cont.4 "YES": C-Ring OK Cont.1 "??"
